My invention has relation toimprovonients vin rearing tonoporating pumps.

"lhe essential. 'feature ot` my invention is the employment of self-reversible meeha'nisin to he used in connection with a pump-piston, wherein by turning a e'rank-liaudle eout'uuf ouslyin one direction the piston and plunger of the pump will he alternately raised and lowered.

In the mechanism herein set forth, the combination of the frame-Work,a revoluble automatically-reciprocating vertical screwthreaded shaft adapted to be attached Ato a pump-plunger, and reversiblyoperatin g vtially as describedY In't-he mechanism herein set forth, the

By this motion the shaft D rises through the medium of the screw-surface d .thereof coacting with the block d2, and consequentljT the plunger F is raised in chamber G, acting upon the valves thereof, as lwill be readily understood. When the teeth of the left-hand gear B cease to be in mesh 'with wheel C', the parts areso timed that said wheel C is immediatelyengaged by the teeth of the right-hand gear B and 'the motion of the parts, as above set forth, reversed, thus forcingthe plunger downward in the cylinder. It will be understood that the shaft B is Irevolved but in onev direction continuously, the reversal of vmotion being controlled by the gears B. As the shaft D rises and lowers, it moves through gear D', mounted thereon, which is allowed ,through the spline-andgroove connection of said parts. l The saidl wheel 1) revolves at the same time that .the shaft I) is passing therethrough. The space between strips A? and A4 is of such width as to cause a continual mesh of thesaid wheel D with gear ("i. By this means an'ytendencyto disengagement of said wheels is prevented and a continuousrevolution in either direction is sustained, and the general operation of the pump thereby made effective. Any tendency of the shaft l) to slip is also avoided lth rough the positive engagement of the-screw-surface d thereof with the set-block (Pon strip A3.
